How to check all the available hard disks (including not in use) in redhat linux

Hi,

I have a DL380 machines running RHEL3. There are 4x300GB and 2x36GB Hard disks are installed in the machine. But only one hard disk is in use. Please let me know how can I check whether the other hard disks are detected by OS and how to use those.

Thanks in advance

either use dmesg or you can apply command

#fdisk -l

it will show your available hard disks, both partitioned and non parttitioned.

Consider that these devices can be used as RAW devices, and also, that may be in a hardware RAID configuration.

Yep, as ahsan says easy way would be using fdisk -l command. but if u need a graphical representation Hardware browser tool will help you.

/proc/partitions will shows only the partitions available. but fdisk -l will show you the total space of a HDD along with partitions.

i think you got your answer.

So, assign points to cheer!!!!!!!!
